           Summary: Kontact thinks that it is already running after
                    starting new KDE session
           Product: kontact
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: etienner at gmail.com


Application that crashed: kontact
Version of the application: 4.3.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
After booting up my system, logging-in in KDE. The following message appears:

"Kontact already seems to be running on another display on this machine.
Running Kontact more than once can cause the loss of mail. You should not start
Kontact unless you are sure that it is not already running."

Then I have two options either "Exit" ot "start", if I press start, The Kmail
icon in the systemtray appears two times. If I right click on one of them, and
then "Quit", Kontact crashes.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
